Edmonton, AB (Sports Network) - Kevin Shattenkirk registered a power-play goal and two assists, as the St. Louis Blues remained hot on the road with a 5-2 win over the Edmonton Oilers.

Andy McDonald scored two goals for the Blues, who have won each of their first four stops on a six-game trek and tied Detroit for first place in the Central Division.

Jaroslav Halak made 22 saves to match St. Louis batterymate Brian Elliott with 20 wins. It marks the first time in Blues history that two goalies have posted at least 20 wins in a season.

Rookie Ryan Nugent-Hopkins and Corey Potter lit the lamp for Edmonton, which entered Wednesday's game having won three of four. Devan Dubnyk surrendered three goals on 19 St. Louis shots before being replaced by Yann Danis, who recorded 10 saves in his first NHL appearance this season.

McDonald opened the scoring 59 seconds into the game and Nichol doubled the advantage, beating Dubnyk on the stick side with a long shot at the 2:05 mark of the second period.

The Blues went up 3-0 on McDonald's second tally, catching the Oilers in the middle of a line change. Shattenkirk retrieved a puck in the St. Louis zone and sent a long pass to T.J. Oshie at the Edmonton blueline. He then passed it to the slot for McDonald, who swept a backhander past Dubnyk at 7:34.

Danis took over between the pipes and the goalie switch seemed to invigorate the Oilers as Potter fired a point shot past Halak at 8:48.

Moments later, Edmonton's Ryan Smyth was assessed a five-minute major for checking from behind and a game misconduct for his hit on St. Louis defenseman Roman Polak.

"Absolutely, there was no intention," Smyth said. "I just tried to ride him in. I thought he was going one way, and he turned the other way and the hit happened."

The Oilers killed the penalty, then drew within a goal when Nugent-Hopkins tapped in a pass from Taylor Hall with 48 seconds left in the middle stanza.

"We struggled on our entry and that just kind of sucked the life out of our power play in general and that gave them some momentum and that kind of changed that period," McDonald said."We talked about it after the second and we had a good response in the third to turn it back around."

Shattenkirk restored St. Louis' two-goal lead, cutting to the crease and directing Alex Pietrangelo's pass into the net at 3:28 of the third period.

Chris Stewart completed the scoring by beating Danis on a penalty shot at 7:54.
